Let's make this birthday one to remember.

81 years old (Born on June 28, 1943)

Happy Birthday, Donald Johanson! Here's to the paleoanthropologist who truly knows how to dig up a good party. Ever since you and your team unearthed Lucy in 1974, you've been making history—and prehistory—fun again. Who knew that stumbling upon a 3-million-year-old fossil could make someone eternally youthful?

Your founding of the Institute of Human Origins in Berkeley back in '81 proved you're not just great at finding ancient bones but also brilliant at inspiring future generations. May your birthday be filled with laughter, joy, and absolutely no fossilized cake—because even legendary discoverers deserve fresh dessert!
